The detection unit 500 can detect the position information PI of the blood vessel BP existing in the object OB based on the image ultrasound reception signal IUR received by the image guidance probe 100 from among the received ultrasound signals.

Fig. 6 is a diagram for explaining the operation of the calculation unit included in the blood flow measurement system of fig. 1, and fig. 7 and 8 are diagrams for explaining the operation of the selection unit included in the control unit of the blood flow measurement system of fig. 1.
Referring to fig. 1-8, the blood flow measurement system 10 may further include a computing portion 600. The calculation unit 600 may calculate the blood flow velocity based on the first doppler ultrasound reception signal DUR1 received by the first doppler probe 200 from among the reception ultrasound signals and the second doppler ultrasound reception signal DUR2 received by the second doppler probe 300 from among the reception ultrasound signals.
In an embodiment of the present invention, the control part 400 may further include a selection part 410. The selection unit 410 may selectively drive the first and second doppler probes 200 and 300 based on a selection signal SE in the control signal CS. For example, the control signal CS may include a selection signal SE. The select signal SE may include a first select signal SE1 and a second select signal SE2. The selection section 410 may turn on the first selection signal SE1 for driving the first doppler probe 200 and the selection section 410 may turn on the second selection signal SE2 for driving the second doppler probe 300.
In an embodiment of the present invention, the selection unit 410 may alternately drive the first doppler probe 200 and the second doppler probe 300 at driving intervals corresponding to a predetermined time interval. For example, the plurality of times may include first to fifth times T1 to T5, and the driving interval ott may include first to fourth driving intervals ott 1 to ott 4. The first driving interval ott 1 may be a time interval between the first time T1 and the second time T2, and the second driving interval ott 2 may be a time interval between the second time T2 and the third time T3. The third driving interval ott 3 may be a time interval between the third time T3 and the fourth time T4, and the fourth driving interval ott 4 may be a time interval between the fourth time T4 and the fifth time T5. In this case, the selection unit 410 may turn on the first selection signal SE1 to drive the first doppler probe 200 during the first driving interval OTI1, and turn on the second selection signal SE2 to drive the second doppler probe 300 during the second driving interval OTI 2. In the manner described above, the first and second doppler probes 200 and 300 may be alternately driven during the third and fourth driving intervals OTI3 and OTI4.
Fig. 9 is a diagram for explaining a first operation mode and a second operation mode among a plurality of operation modes of the blood flow measurement system of fig. 1, fig. 10 is a diagram for explaining the first operation mode of fig. 9, and fig. 11 is a diagram for explaining a method of calculating cardiac output of the blood flow measurement system of fig. 1.
Referring to fig. 1-11, a blood flow measurement system 10 may operate in a plurality of modes of operation. When the detecting section 500 detects the position information PI of the blood vessel BP, the control section 400 may sequentially increase the transmission interval of the transmission-transmission ultrasonic signal UT in the first operation mode of the plurality of operation modes. For example, after the detection unit 500 accurately detects the position information PI of the blood vessel BP, the detection unit 500 does not need to frequently transmit the transmission ultrasonic signal UT before detecting the blood vessel BP position information PI in order to confirm the position of the BP of the blood vessel inside the object OB.
In this case, the control part 400 may sequentially increase the transmission interval. For example, the plurality of times may include a sixth time T6 to a ninth time T9. The transmission interval may include first to third transmission intervals TI1 to TI3. The first transmission interval TI1 may be a time interval between the sixth time T6 and the seventh time T7, and the second transmission interval TI2 may be a time interval between the seventh time T7 and the eighth time T8. Also, the third transmission interval TI3 may be a time interval between the eighth time T8 and the ninth time T9. In this case, the first transmission interval TI1 may be smaller than the second transmission interval TI2, and the second transmission interval TI2 may be smaller than the third transmission interval TI3. In the same manner, after the detection unit 500 detects the position information PI of the blood vessel BP, the system load can be reduced by gradually increasing the time interval required for realizing the ultrasound image by the image guidance probe 100 so that the blood flow measurement system 10 can perform other works.
In the first mode of operation, the probe for transmitting ultrasonic signals may be the image-guided probe 100, and in the second mode of operation, the probe for transmitting ultrasonic signals may be the first doppler probe 200 and the second doppler probe 300.
In an embodiment of the present invention, when the detecting unit 500 detects the position information PI of the blood vessel BP, the control unit 400 may drive the first doppler probe 200 and the second doppler probe 300 to alternately transmit the first doppler ultrasound transmission signal and the second doppler ultrasound transmission signal to the blood vessel BP existing in the object OB in the second operation mode of the plurality of operation modes. Also, in an embodiment of the present invention, the blood flow measurement system 10 may calculate the blood flow velocity based on the first Doppler ultrasound received signal DUR1 received by the first Doppler probe 200 due to the reflection of the first Doppler ultrasound transmitted signal by the blood vessel BO and the second Doppler ultrasound received signal DUR2 received by the second Doppler probe 300 due to the reflection of the second Doppler ultrasound transmitted signal by the blood vessel BP.
For example, after the detection unit 500 accurately detects the position information PI of the blood vessel BP, the blood flow measurement system 10 of the present invention may concentrate the resources on measuring the blood flow velocity BV of the blood vessel BP. In this case, during the first driving interval OTI1, the first doppler probe 200 driven based on the first selection signal SE1 is used to beam-transmit the first doppler ultrasound transmission signal to the predetermined point set existing in the blood vessel BP, and the first doppler ultrasound reception signal DUR1 received by the first doppler probe 200 due to reflection by the blood vessel BP can be received. Then, during the second driving interval OTI2, the second doppler probe 300 driven based on the second selection signal SE2 is used to transmit the second doppler ultrasound transmission signal to the predetermined point set existing in the blood vessel BP, and the second doppler ultrasound reception signal DUR2 received by the second doppler probe 300 due to reflection by the blood vessel BP can be received. The blood flow measurement system 10 of the present invention can calculate the blood flow velocity BV based on the first doppler ultrasound reception signal DUR1 and the second doppler ultrasound reception signal DUR2.
As can be seen from the mathematical expression shown in fig. 11, when the first doppler probe 200 and the second doppler probe 300 are used, a first spectrogram corresponding to the first blood flow velocity and a second spectrogram corresponding to the second blood flow velocity, which change with time, can be generated without affecting the incident angle, and a velocity time integral (VTI, velocity time integral) can be generated from the spectrograms. In one embodiment of the present invention, the present blood flow measurement system 10 may calculate cardiac output based on the velocity time integral, the cross-sectional area MZ, and the heart rate. Wherein cardiac output can be expressed as the product of the velocity time integral, cross-sectional area MZ, and heart rate.
